CROSS-REFERENCE

This application is the US National Stage of PCT Application No. PCT/CN2017/096118, filed Aug. 4, 2017, and named after “RESOURCE SCHEDULING METHOD, TERMINAL DEVICE, AND NETWORK DEVICE”, the contents of which are hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The application relates to the field of communications, and more particularly to a resource scheduling method, a terminal device and a network device.

BACKGROUND

Internet of vehicles system is a Sidelink (SL) transmission technology based on Long Term Evolution (LTE) Device to Device (D2D). Unlike a conventional LTE system which receives or sends communication data through a base station, an Internet of vehicles system adopts D2D communication and thus is higher in spectrum efficiency and lower in transmission delay.

In 3rd Generation Partnership Project (3GPP) Release 14 (Rel-14), a Vehicle to Vehicle (V2V) technology is standardized, and two transmission modes are defined: mode 3 and mode 4. In the mode 3, a transmission resource of Vehicle User Equipment (VUE) is allocated by a base station, and the VUE performs data transmission with other VUE on an SL according to the resource allocated by the base station. Moreover, a resource for single transmission may be allocated by the base station to the VUE and a resource for semi-persistent transmission may be also allocated to the VUE.

For a Carrier Aggregation (CA) scenario, a terminal device supports data duplication. A duplicated Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU) is transmitted through a data duplication function of PDCP to two Radio Link Control (RLC) entities, namely corresponding to two different logical channels, and it is finally ensured that the duplicated PDCP PDU may be transmitted on different physical aggregated carriers, thereby achieving a frequency diversity gain to improve reliability of data transmission.

In addition, a terminal device may transmit some specific services through short Transmission Time Intervals (sTTIs). For example, the sTTI may be 0.5 ms, which indicates that the terminal device adopts a 0.5 ms resource for transmission. Compared with a conventional 1 ms resource, the granularity of 0.5 ms resource improves delay performance.

However, for the CA scenario or a scenario where service data is transmitted through an sTTI, a process that a base station configures a transmission resource is not defined in a conventional art.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the application will be described below in combination with the drawings.

It is to be understood that the technical solutions of the embodiments of the application may be applied to various communication systems, for example, an LTE system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, a 4.5th Generation (4.5G) network, a 5th Generation (5G) network and New Radio (NR). The embodiments of the application may also be applied to a Vehicle to Everything (V2X) system such as a V2V system, or may further be applied to a D2D system. The embodiments of the application are not limited thereto.

It is to be understood that a network device involved in the embodiments of the application is a device deployed in a Radio Access Network (RAN) to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include macro base stations, micro base stations, relay stations, access points and the like in various forms. In systems adopting different radio access technologies, a device with a base station function may have different names. For example, it is called an Evolved NodeB (eNB or eNodeB) in an LTE network, and is called a Node B in a 3rd Generation (3G) network, etc.

It is to be understood that the terminal device in the embodiments of the application may also be called a terminal, User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT) and the like. The terminal device may be VUE, for example, a vehicle or a wireless terminal for self driving. Or, the terminal device may also be Pedestrian User Equipment (PUE), for example, a mobile phone, a pad, a computer with a wireless transceiver function, or the like.

FIG. 1 is a schematic diagram of an Internet of vehicles system according to an embodiment of the application. As shown in FIG. 1 , the embodiment of the application may be applied to various application scenarios. Here, descriptions are made with a network device and a terminal device in the Internet of things system as an example. The network device may be an eNB, the terminal device may be VUE, and the VUE includes vehicle 1 and vehicle 2.

In 3GPP Rel-14, a V2V technology is standardized, and two transmission modes are defined: mode 3 and mode 4. In the mode 3, a transmission resource of VUE is allocated by a base station, and data transmission is performed between the VUE and another VUE on an SL according to the resource allocated by the base station. Moreover, the base station may allocate a resource for single transmission to the VUE and may also allocate a resource for semi-persistent transmission to the VUE.

For example, as shown in FIG. 1 , the eNB may configure a granted resource for the vehicle 1 and may transmit resource grant information indicative of the granted resource through a Down Link (DL) in FIG. 1 . The vehicle 1 determines the granted resource and transmits data to the vehicle 2 through an SL by use of the granted resource. Or, the eNB may also configure a granted resource for the vehicle 2 through the DL, and then the vehicle 2 transmits data to the vehicle 1 through the SL by use of the granted resource.

FIG. 2 is a schematic flowchart of a method 100 for resource scheduling according to an embodiment of the application. The method 100 may be executed by a terminal device and, for example, may be executed by the VUE shown in FIG. 1 , and the VUE may be the vehicle 1 or vehicle 2 in FIG. 1 .

As shown in FIG. 2 , the method 100 includes the following operations. In S110, a first terminal device receives indication information and resource grant information from a network device, the resource grant information being to indicate a granted resource allocated to the first terminal device by the network device, and the indication information being to indicate that the granted resource is configured to transmit data born on a target logical channel. In S120, the first terminal device transmits the data born on the logical channel to a second terminal device through the granted resource according to the indication information and the resource grant information.

It is to be understood that the first terminal device and the second terminal device may be any terminal devices, the first terminal device may be one or more terminal devices, for example, a group of terminal devices, and similarly, the second terminal device may also be one or more terminal devices, for example, a group of terminal devices. The embodiment of the application is not limited thereto.

In the embodiment of the application, the granted resource occupied by data sending of the first terminal device to the second terminal device may be configured through the network device, namely the first terminal device may transmit the data to the second terminal device through the granted resource configured by the network device. For example, the first terminal device may be a terminal device working based on Rel-14, and the first terminal device may be in the mode 3.

It is to be understood that the method 100 may be applied to duplication and transmission in a CA scenario. The duplication and transmission may refer to a duplication function of a PDCP layer, i.e., duplicating data of a PDCP PDU and transmitting the PDCP PDU data through two RLC entities. Or, the duplication and transmission may refer to duplicating data of a PDCP Service Data Unit (SDU) and transmitting the duplicated data through two PDCP entities respectively. The embodiment of the application is not limited thereto.

Optionally, the duplication and transmission may refer to duplicating data of a PDCP PDU. Specifically, FIG. 3 is a schematic diagram of duplication and transmission of PDCP data according to an embodiment of the application. As shown in FIG. 3 , one PDCP entity is bound with two RLC entities. The terminal device duplicates a first PDCP PDU which is to be transmitted to obtain a second PDCP PDU. The terminal device transmits the first PDCP PDU to one RLC entity which is called RLC1 in the two RLC entities and transmits the second PDCP PDU to the other RLC entity which is called RLC2 in the two RLC entities. The two RLC entities process the received PDCP PDUs respectively. The first PDCP PDU and the second PDCP PDU, after passing through a MAC layer, are transmitted to the network device through two different carriers, for example, as shown in FIG. 3 , through physical carrier 1 and physical carrier 2 respectively. A process that the two RLC entities process the received PDCP PDUs is the same as a manner adopted by a single RLC entity to process a PDCP PDU in case of no duplication in the conventional art and will not be elaborated herein.

It is to be understood that the duplication and transmission may include duplication and transmission of a Signaling Radio Bearer (SRB) and/or a Data Radio Bearer (DRB).

In S110, the first terminal device receives the indication information and resource grant information from the network device, the resource grant information being to indicate the granted resource allocated to the first terminal device by the network device and the indication information being to indicate that the granted resource is configured to transmit the data born on the target logical channel.

In the embodiment of the application, the network device configures the granted resource for the first terminal device and may further indicate, through the indication information, a specific logical channel where the data may be transmitted through the granted resource to the first terminal device. For example, for the CA scenario, the first terminal device may perform data duplication and transmission, and then the network device may indicate to the terminal device through the indication information whether the granted resource may be configured to transmit duplicated data or not. Specifically, the indication information may indicate that the granted resource is configured to transmit the data of the target logical channel. If the target logical channel can transmit the duplicated data, the granted resource is configured to transmit the duplicated data; otherwise, if the target logical channel cannot be configured to transmit the duplicated data, the data transmitted through the granted resource and born on the target logical channel is non-duplicated data.

Optionally, the network device may further indicate to the terminal device, through the indication information, whether to bear the duplicated data through the target logical channel or not.

Specifically, for the CA scenario, when there is duplicated data required to be transmitted in the first terminal device, a network device may indicate that the duplicated data is transmitted through multiple logical channels in the first terminal device and the duplicated data may further be transmitted through the granted resource configured by the network device. Specifically, for any terminal device, the terminal device may be called a first terminal device, and duplicated data may be transmitted in the first terminal device. The network device may configure the granted resource for the first terminal device, and the granted resource may be a resource for transmitting the duplicated data, namely the granted resource may be configured to transmit data corresponding to different logical channels, the different logical channels corresponding to the same data bearer; or the granted resource may also be a resource not for transmitting the duplicated data, namely the granted resource is configured to transmit other data than the duplicated data. The network device may transmit the indication information and the resource grant information to the first terminal device, the resource grant information being to indicate the granted resource allocated to the first terminal device by the network device and the indication information being to indicate whether the granted resource may be configured to transmit the duplicated data or not, namely whether the granted resource may be configured to transmit the same data bearer corresponding to different logical channels or not.

In S120, the first terminal device transmits the data born on the target logical channel to the second terminal device through the granted resource according to the indication information and the resource grant information.

Optionally, the indication information may indicate that the granted resource may not be configured to transmit the duplicated data, and then the first terminal device may transmit other data than the duplicated data to the second terminal device through the granted resource. For example, the granted resource may be configured to transmit the data born on the target logical channel, and the data born on the target logical channel is not duplicated data.

Optionally, as an embodiment, the indication information may be configured to indicate that the granted resource may be configured to transmit the duplicated data, namely the first terminal device may transmit the same data bearer corresponding to different logical channels to the second terminal device through the granted resource. Specifically, the duplicated data may correspond to a first logical channel and a second logical channel respectively, the first logical channel and the second logical channel corresponding to the same data bearer. The granted resource may include a first granted resource and a second granted resource, and the target logical channel may include a first logical channel and a second logical channel. The first granted resource may be configured for the first terminal device to transmit data corresponding to the first logical channel to the second terminal device, and the second granted resource may be configured for the first terminal device to transmit data corresponding to the second logical channel to the second terminal device.

Specifically, descriptions will be made below with the condition that the first terminal device may transmit the duplicated data as an example. Moreover, the network device may configure the granted resource for the first terminal device, the granted resource being configured to transmit the duplicated data. The first terminal device may receive the resource grant information and the indication information. Before transmitting the duplicated data through the granted resource, the first terminal device may determine a first corresponding relationship between the first logical channel and the first granted resource and a second corresponding relationship between the second logical channel and the second granted resource.

Optionally, as an embodiment, the first terminal device may determine a corresponding relationship between the first logical channel and a first carrier and a corresponding relationship between the second logical channel and a second carrier at first. Specifically, the first terminal device may receive information of the second corresponding relationship from the network device, and the first terminal device may determine the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier according to the information of the second corresponding relationship. Or, the first terminal device may independently determine the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier and transmit information of a third corresponding relationship to the network device, the information of the third corresponding relationship being for the network device to determine the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier, such that the network device may further determine the first granted resource corresponding to the first logical channel and the second granted resource corresponding to the second logical channel.

Optionally, the first terminal device may receive the information of the second corresponding relationship transmitted by the network device and determines the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier according to the information of the second corresponding relationship. Specifically, the information of the second corresponding relationship transmitted by the network device may be RRC signaling, a MAC CE or DCI. In addition, the information of the second corresponding relationship may indicate the corresponding relationships based on a granularity of logical channel, a granularity of logical channel group or a granularity of destination address, namely the information of the second corresponding relationship may include a corresponding relationship between a carrier and a logical channel, a logical channel group or a destination address. The embodiment of the application is not limited thereto.

For example, the information of the second corresponding relationship may adopt the granularity of logical channel, namely the information of the second corresponding relationship may include a corresponding relationship between multiple logical channels and multiple carriers, and the multiple logical channels may include the first logical channel and/or the second logical channel, namely the information of the second corresponding relationship may include the corresponding relationship between the first logical channel and the first carrier and/or the corresponding relationship between the second logical channel and the second carrier. Then, the first terminal device, according to the information of the second corresponding relationship, may map the data born on the first logical channel onto the first carrier and map the data born on the second logical channel onto the second carrier. The first carrier and the second carrier may be any two different carriers.

For another example, the information of the second corresponding relationship may adopt the granularity of logical channel group, namely the information of the second corresponding relationship transmitted by the network device may include a corresponding relationship between at least one logical channel group and a carrier. Specifically, the at least one logical channel group may include a first logical channel group and/or a second logical channel group. If the at least one logical channel group includes the first logical channel group, namely the information of the second corresponding relationship may include a corresponding relationship between the first logical channel group and the first carrier, the first logical channel group may include n logical channels, the n logical channels include the first logical channel and do not include the second logical channel and all the n logical channels correspond to the first carrier, the first terminal device may determine the corresponding relationship between the first logical channel and the first carrier. If the at least one logical channel group includes the second logical channel group, namely the information of the second corresponding relationship may include a corresponding relationship between the second logical channel group and the second carrier, the second logical channel group may include m logical channels, the m logical channels include the second logical channel and do not include the first logical channel and all the m logical channels correspond to the second carrier, the first terminal device may determine the corresponding relationship between the second logical channel and the second carrier. Both n and m are positive integers greater than 1.

It is to be understood that the information of the second corresponding relationship may also include both a corresponding relationship between a logical channel and a carrier and a corresponding relationship between a logical channel group and a carrier. For example, the information of the second corresponding relationship may include the corresponding relationship between the first logical channel group and the first carrier, the first logical channel group including the first logical channel, and then the first terminal device may determine the corresponding relationship between the first logical channel and the first carrier. The information of the second corresponding relationship may also include corresponding relationship information between one or more logical channels and one or more carriers and does not adopt the granularity of logical channel group, and the first terminal device may further determine the corresponding relationship between the second logical channel and the second carrier. However, the embodiment of the application is not limited thereto.

Optionally, the first terminal device may independently determine the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier. The first terminal device may transmit information of a third corresponding relationship to the network device and indicate the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier through the information of the third corresponding relationship. Specifically, the information of the third corresponding relationship transmitted to the network device by the first terminal device may be RRC signaling, a MAC CE or DCI.

In addition, the first terminal device may determine the corresponding relationship between the logical channel and the carrier and report the same to the network device through the information of the third corresponding relationship. The information of the third corresponding relationship may also indicate the corresponding relationship based on the granularity of logical channel, the granularity of logical channel group or the granularity of destination address, namely the information of the third corresponding relationship may include the corresponding relationship between a logical channel, a logical channel group or a destination address and a carrier. The embodiment of the application is not limited thereto. For example, the information of the third corresponding relationship may adopt the granularity of logical channel, namely the information of the third corresponding relationship may include a corresponding relationship between multiple logical channels and multiple carriers, and the multiple logical channels include the first logical channel and/or the second logical channel, namely the information of the third corresponding relationship includes the corresponding relationship between the first logical channel and the first carrier and/or the corresponding relationship between the second logical channel and the second carrier, the first carrier and the second carrier being any two different carriers, such that the network device may determine the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier according to the information of the third corresponding relationship.

For another example, the information of the third corresponding relationship may adopt the granularity of logical channel group, namely the information of the third corresponding relationship transmitted to the network device may include a corresponding relationship between at least one logical channel group and a carrier. Specifically, the at least one logical channel group may include a third logical channel group and/or a fourth logical channel group. If the at least one logical channel group includes the third logical channel group, namely the information of the third corresponding relationship may include a corresponding relationship between the third logical channel group and the first carrier, the third logical channel group may include k logical channels, the k logical channels include the first logical channel and do not include the second logical channel and all the k logical channels correspond to the first carrier, then the network device may determine the corresponding relationship between the first logical channel and the first carrier. If the at least one logical channel group includes the fourth logical channel group, namely the information of the third corresponding relationship may include a corresponding relationship between the fourth logical channel group and the second carrier, the fourth logical channel group may include l logical channels, the l logical channels include the second logical channel and do not include the first logical channel and all the l logical channels correspond to the second carrier, then the network device may determine the corresponding relationship between the second logical channel and the second carrier. Both k and l are positive integers greater than 1.

It is to be understood that the information of the third corresponding relationship may also include both the corresponding relationship between a logical channel and a carrier and the corresponding relationship between a logical channel group and a carrier. For example, the information of the third corresponding relationship may include the corresponding relationship between the first logical channel group and the first carrier, the first logical channel group including the first logical channel, and then the network device may determine the corresponding relationship between the first logical channel and the first carrier. The information of the third corresponding relationship may also include corresponding relationship information between one or more logical channels and one or more carriers and does not adopt the granularity of logical channel group, and the network device may further determine the corresponding relationship between the second logical channel and the second carrier. However, the embodiment of the application is not limited thereto.

In the embodiment of the application, the first terminal device determines the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the second logical channel and the second carrier, the first terminal device may further receive the information of the first corresponding relationship transmitted by the network device and determine the corresponding relationship between the first carrier and the first granted resource and the corresponding relationship between the second granted resource and the second carrier according to the information of the first corresponding relationship, and then the first terminal device may determine the first corresponding relationship between the first granted resource and the first logical channel according to the corresponding relationship between the first logical channel and the first carrier and the corresponding relationship between the first carrier and the first granted resource and, similarly, may also determine the second corresponding relationship between the second granted resource and the second logical channel according to the corresponding relationship between the second logical channel and the second carrier and the corresponding relationship between the second carrier and the second granted resource.

Specifically, the information of the first corresponding relationship received by the first terminal device from the network device may be born on a control channel. Optionally, the first terminal device may also acquire the indication information through control information, the indication information being to indicate whether the granted resource may be configured to transmit the same data bearer corresponding to different logical channels or not. The first terminal device may further acquire the resource grant information through the control information, the resource grant information being to indicate the granted resource allocated to the first terminal device by the network device. However, the embodiment of the application is not limited thereto.

Optionally, as an embodiment, the first terminal device may receive information of a fourth corresponding relationship transmitted by the network device and directly determine the first corresponding relationship between the first logical channel and the first granted resource and the second corresponding relationship between the second logical channel and the second granted resource according to the information of the fourth corresponding relationship.

It is to be understood that the information of the fourth corresponding relationship received by the first terminal device may include the first corresponding relationship between the first logical channel and the first granted resource and the second corresponding relationship between the second logical channel and the second granted resource. Specifically, the fourth corresponding relationship may include a Logical Channel Identity (LCID) of at least one logical channel, the at least one corresponding logical channel is determined according to the LCID of the at least one logical channel, and a data duplication function of the at least one logical channel is in an on state, namely data born on the at least one logical channel is duplicated data.

A corresponding relationship between the at least one logical channel and a granted resource may be included in the information of the fourth corresponding relationship and used to indicate that the granted resource may be configured to transmit the data corresponding to the at least one logical channel and including the first corresponding relationship between the first logical channel and the first granted resource and the second corresponding relationship between the second logical channel and the second granted resource. For other logical channels that are not indicated, it is considered as a default that data duplication and transmission are not supported or the data duplication and transmission function is off, namely data born on other logical channels may be transmitted on any other granted resources. The first terminal device may determine according to the information of the fourth corresponding relationship that the first granted resource is configured to transmit the data born on the first logical channel, and the second granted resource is configured to transmit the data born on the second logical channel.

Optionally, the information of the fourth corresponding relationship received by the first terminal device from the network device may be born on a control channel. Optionally, the first terminal device may also acquire the indication information through control information, the indication information being used to indicate whether the granted resource may be configured to transmit the same data bearer corresponding to different logical channels or not. The first terminal device may further acquire the resource grant information through control information, the resource grant information being used to indicate the granted resource allocated to the first terminal device by the network device. However, the embodiment of the application is not limited thereto.

Specifically, the information of the fourth corresponding relationship may be control information born on the control channel, and the first terminal device may contain a bitmap corresponding to all LCIDs supported by the first terminal device in the control information in the control channel. For example, if there are totally 16 logical channels for the first terminal device, the control information contains a 16 bit bitmap. For values in the bitmap: 0 may indicate that the granted resource is unavailable for the corresponding logical channel and 1 may indicate that the granted resource is available for the corresponding logical channel. In addition, all the logical channels for which the granted resource is indicated by the bitmap to be available may be logical channels that may be configured to transmit duplicated data or logical channels that may not be configured to transmit duplicated data.

In such a manner, according to the resource scheduling method of the embodiment of the application, the terminal device determines a granted resource available to transmit duplicated data through indication information and the granted resource which are transmitted by the network device and transmits the duplicated data to another terminal device through the granted resource, so that resource allocation for transmission of duplicated data in the CA scenario is implemented.

In S320, the first terminal device determines according to the information of the first corresponding relationship that the granted resource is a resource for transmitting data based on a specific TTI. In S330, the first terminal device determines a target logical channel corresponding to the specific TTI.
